Non-negative Tensor Factorisation for Sound Source Separation
Document Type Conference Paper
Proceedings of the Irish Signals and Systems Conference, Dublin, Ireland, 2005.
An algorithm for Non-negative Tensor Factorisation is introduced which extends current matrix factorisation techniques to deal with tensors. The effectiveness of the algorithm is then demonstrated through tests on synthetic data. The algorithm is then employed as a means of performing sound source separation on two channel mixtures, and the separation capabilities of the algorithm demonstrated on a two channel mixture containing saxophone, strings and bass guitar.
